approval/decline reminder emails: what is the number after issueKey in URL?

[llagos]

Hello!

We've setup a series of reminder emails after an issue is Resolved, to kind of force the Reporter to either approve or decline the resolution, and get the issue Closed.

Problem is, those are emails based on SLAs so there is no Approve/Decline buttons.

What we'd like to do is add just two links, for approve or decline, using placeholder ${request.key}, sort of:

http://.../servicedesk/customer/user/approval-action/${request.key}/###number###/approve/analytics

http://.../servicedesk/customer/user/approval-action/${request.key}/###number###/reject/analytics

Problem is there is number, which we haven't identified, after the key... what is this number?

It changes from issue to issue...

Thanks a lot!
